Analysis

On May 1, 2026, about 1910 eastern daylight time, a North American Navion, N8618H, was substantially damaged when it was involved in an accident near New Salem, Massachusetts. The pilot received minor injuries. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight.

According to the pilot, he conducted a routine preflight inspection, which included flight controls, oil level, and fuel sump checks. Following his inspection, he started the aircraft and taxied to the runway run-up area. The before takeoff checks were normal with no abnormalities observed before departure.

After departure, the pilot climbed to 1,700 ft mean seal level and proceeded south toward Quabbin Reservoir. Upon reaching the reservoir, he turned north toward the airport. Shortly thereafter, while in straight and level flight, the engine lost all power. The pilot established best glide speed and attempted to restart the engine without success. Realizing he could not reach the airport, and considering the local roadway traffic, tree coverage, and powerlines, he decided, the safest option was to ditch the airplane in the reservoir.

During the approach, the airplane struck trees before touching down on the surface of the water. The airplane subsequently began to sink, and the pilot egressed through the sliding canopy. The airplane sustained substantial damage to the fuselage, empennage and wings.

The wreckage was recovered and retained for further examination.
